This popular site has many attractions including a plane and other items of interest. The water is typically very cold though at any depth so a two layer wetsuit is required with a hood and gloves.

The fee is $20 for entry (cash) to be paid to the quarry owners and a valid FQAS card is required. This can be acquired at local dive shops but may require a course to acquire depending on the shop. In fall 2021, Scuba Finatics ( https://scubafinatics.ca/) seemed to be the best source for these cards. Plan well in advance if you need a new or updated FQAS card.
